About

Dr. Keqin Gu is a leading figure in control theory and engineering education, best known for pioneering work on the stability of time-delay systems. His research focuses on the complex dynamics of systems where feedback signals are subject to delays—a critical challenge in robotics, networked control, and industrial automation. Dr. Gu’s most influential contribution is his development of rigorous analytical frameworks for delay-difference feedback, which provide engineers with precise tools to determine stability boundaries in systems with both state and coefficient delays. His 2017 paper on this topic (9 citations) remains a foundational reference for researchers tackling delay-induced instability. Beyond theory, Dr. Gu is a champion of hands-on, multidisciplinary education. His highly cited 2020 paper (60 citations) presents a model for integrating low-cost robotics into engineering curricula, demonstrating how robot kits can unify instruction across electrical, mechanical, and software disciplines. This work has reshaped how universities approach project-based learning, making complex systems accessible to undergraduates. With a career spanning both deep theoretical advances and practical pedagogical innovation, Dr. Gu’s research continues to inspire students and engineers to bridge the gap between abstract control mathematics and real-world robotic applications.
